To all whom it may concern it known that l, WALTER C. Benn, a

citizen of the lilnitecl States, and a residentot Toledo, county of Lucas, and State ()l' t tlhio, have invented a new and usetul linprovenient in lleinountable litims, oil? which the following is a speciiication the principle of the invention being herein explainetl and the best mode in which I have contemplated n applying that principle, so as to distinguish it from other inventions.

My invention relates to @emountahle rim to he used on wheels, ahel is parties larly adapted to automobile Work by reason of its quick and convenient adjustment.

Various rims of this type have of course, been in general use for some time,,,!but all oi them present several clisarlvantages. litany of these rims are extremely heavy in 're light are not sutliciently strong and positive in engagement to stand up under the extremely rough usage to which they arc yiubjectecl. The present riin entirely overcotues these objections, ancl may, of course, be/usecl with any type of so-called quick-d/etachahlef rim clesirecl.

To the accomplishment of these ancl related ends, said invention, then, consists of the means hereinafter fully described and par ticularly pointed out in the claims.

The anner'liel drawing and the tollo'wiug description set forth in detail certain mechanism embmlying the invention such clisclosed means constituting, however, but one of the various mechanical forms in which the prmcipie of the invention may be used. In said annexed drawing: Figure l is a siole elevation of my demountablc rim in placeon avehicle wheel; Fig. 2 is plan View showing the operating mechanism; i in. 3 is a sectional view on the line 3-3 in Fig. 2; Figs. 4, 5 and 6 are sectional views showing various forms which the engaging;

and may befixcclly attached to a wheel.

Upon this fixed rim there may be engaged a second rim 3 which is securely held thereon by means of a circumferentially movable member at mounted upon the fixed rim. At

several points in the onion flange of the fixed rim are openings 5 which will be enlugs may take; Fig. 7 is a plan view simigaged by lugs 6 mounted on the uncier side of the seconri rin'n the second rim forced into place, these lugs (twill en g'e e complementary lugs 'l' mounted upon the fired riin. 'll'fhe lugs be 'n'ra'. e(lL as shown in Fi it. or tile may several forms, as shown in Figs, ll. either case the lugs upon the inert rim slope out wardly and wilovrnivarrliy. The log on the r movable rin'i will Slope in corresponding (Prection in" (letter to securely the fired lug; asi the removable, is forced into place. This engagement must be or treniely Beel ne as the driving); ot the renterable rim by means of the lineal rim will 01' course, be matle largely throa gh this on gageinent. Also, lugs 6 may bemacie to en? gage the thing: on the inner side of fixecl rim and thus provide the nemessary driving" connection.

The circuinferentia lly movable meinher in the form of a circular ring which i 'reely movable around the surface of the tired rim adjacent to the outer flange. lit has apertures 8 which correspond 'to the apertures in the flange oil the tired rim, and upon a slight circumferential movement these apertures are adapted to coincide,thus permitting the insertion of the lugs upon the removable rim. Adjacent to these apertures on the member are mounted inclinerl treinely simple and positive means consists ot'the members short-i1 in Fig. 1, via, a screw 10 mounted transversely oi. the tirecl rim in the flanges thereofanrl engaging a member 11, having grooves 12 which are engaged by the curl 13 of a hell-crank member 14: pivotally mounted on the pin 15. The other end 16 of: this bell-crank engages the movable member by means of a loose socket joint-'18, and. its-the" screw is rotated by any suitable means which maybe adapted to engagc the bolt-head on the end of the screw. the bell-crauirgis rotated and. thus terms the movable member circumteren tially around the fixed riin. l hen so moved, this member trill entirely close the apertures in the outer flange, tl us securely and positively locking the removable rim in 15121012,:11141 at the same time preventing circumterentially around the rirn but an en till fill

the entrance of dirt and water into the space bct eon the removable and the fixed rims.

In the modified form shown in i, L provide gears 21, --which are adapted to move the member circumferentially around the rim, as will be readily understood. These and various other constructions may be used for the purpose of moving the cir cumt'ercn tiai member, but it is thought that the simplest and best means of accomplishing this purpose are the means shown in Fig. Land described above.

No claim is made to any type of tire re removable rim, and it will be clear that any suitable form may be used for My demountable rim possesses several. advantages. It is positive in engagement and disengagement. Itis extremely simple to operate, there being only one bolt or screw, and by reason of the closing of the apertures in the outer flange of the fixed rim, no dirt or water can gain entrance to the inner space, thus preventing wear and rust and re taining the mechanism in good COIlCiic-lOYi, rendering the operation easy and convenient,

Other modes oi"? applying the principle or". my invention may be employed instead of the one explained, change being made as re gards the mechanism herein disclosed, pre vided the means stated by any of the following claims or the equivalent of such stated means be employed.

1 therefore particularly point out and distinctly claim my invention 1. in device of the class described, the m mbiimtion of a fixed rim having lugs on its outer surface and upturned flanges on its inner and outer edges, such outer flange having openings therein; a second rim hav ing lugs adapted to enter such openings in such outer flange and engage with such lugs on said fixed rim; a circumiercntially mop able member mounted on said fixed rim adjacent to such outc" flange, said movable member having inclined lugs adapted when said member is rotated, to contact such lugs, thereby \vedging said second rim in such engagement; and suitable means inclc-scd in said fixed rinffor actuating said movable member.

in device of the class described, the combin [1071 ofa fixed rim having; mved lugs on its outer surface and rned flanges on its inner and outer edges, such outer flange having openings; a second rim having lugs with raised portions adapted to it in the grooves of such grooved lugs, such lugs adapted to enter such openings in such outer flange and engage with such grooved lugs; a circulnferentially movable member tll's purpose.

, 4 I i I mounted on said fixed rim adjacent to said outer flange, said movable member having inclined lugs adapted, when said member is rotated, to contact such aforementioned lugs,

thereby wedging the same in such engage-- flanges at its inner and outer. edges, such outer flange having openings therein; a second rim having; lugs adapted to enter such openings in such outer flange, and engage with such lugs on said fixed. rim; a circumferentially movable member mounted on said fixed rim adjacentto said flange, said movable member having inclined lugs and adapted when said member is rotated to contact such lugs and wedge-said second rim insuch cngagem ent, said movable member being adapted when in looking position to cover sue openings in said flanges; and suitable means inclosed in said fixed rim for act iating said movable member.

In a device of the character described,

the combination of a fixed rim having grooved lugs on its outer surface, and upturned flanges at its inner andouter edges, such outer flange having openings therein; a second rim having lugs with raised 'portions on its inner surface, such lugsvvith raised portions adapted to enter such'openings engage with such grooved lugs; a circinuferentially movable locking member mounted on said fixedrim adjacent to such outer flange, said member having inclined lugs adapted, when said member is rotated, to wedge such lugs in such engagement, said member 1 adapted to close such openings when in in king position; and suitable means inclosed in sai fixed rim for rotating said movable member.

in a device of the class described, the

l combination of a fixed rim having upturned flanges, a second rim adapted to removably engage said fixed rim, 2. member mounted on said fixed rim and movable circumferentially thereon, and, means including a threaded bolt, and a bellcrank lever pivotally mounted on said! fixed rim and adapted to be actuated by said bolt, said lever being connected to said member and actuating the same, whereby said member, when so actuated locks said removable rim securely on said iiXQ-d rim.
